Definitions

  • THIS INVENTION relates to a conveyor roller or idler.
  • the conveyor rollers are difficult to assemble and disassemble.
  • the conveyor roller comprises a drum having locating formations formed on or attached to the inner wall of the drum.
  • Bearing assemblies are adapted to engage the formations on assembly of the roller. Exact location of the bearing assembly relative to the formations is frequently a problem. This problem generally tends to increase the cost of the idlers as well as increasing the cost of maintaining the conveyor. Where a conveyor roller needs to be repaired, the time necessary to effect repairs is important because down time of the conveyor generally means interruption of the process wherein the conveyor, is used.
  • a conveyor roller comprising a right circular cylindrical tubular member supported on a shaft by an end cap located in at least one end thereof, the end cap having an axial hole therethrough and a co-axial bearing located therein by means of which the tubular member is rotatably supported on the shaft, the end cap including first and second relatively movable cooperant portions at least one of which has a tapered surface, means being provided to urge the two portions into cooperant engagement, the tapered surface, on engagement being adapted to urge one of the portions radially outward and into frictional engagement with an inner wall of the tubular member to thereby secure the end cap in position in the tubular member.
  • the end cap to comprise a plastics body having the f-irst portion integrally formed therewith, the second portion being movable relative to the first portion.
  • the second portion will comprise an annular member having a surface adapted to cooperate with the tapered surface of the first portion.
  • the second portion may include the tapered surface or both portions may have cooperantly tapered surfaces.
  • the means will preferably comprise a plurality of screws which are located in holes formed in the end cap and evenly spaced around the central axis thereof, the screws being engaged in threaded holes formed in the second portion, rotation of the screws in use being adapted to move the two portions into and out of engagement in use.
  • the outer edge of the plastics material may have a locating formation formed thereon to ensure aligned engagement with the tubular member.
  • the invention also provides for the bearing to be sealed by a labyrinth seal or other suitable sealing means; for there to be a plurality of bearings encapsulated in the plastics material; for the plastics material to be polyurethane; and for there to be three screws circumferentially spaced around the central axis.
  • the invention extends to an end cap for insertion into a conveyor roller as hereinbefore described.
  • the tubular member may be formed from steel of the like, or alternatively from a suitable plastics material. Specifically envisaged in this regard is an unplasticised polyvinylchloride (uPVC) which is sufficiently rigid and strong for this type of application. Also, it will be possible for the tubular member to be formed of an outer sleeve of plastics material and an inner sleeve of metal.
  • uPVC unplasticised polyvinylchloride
  • a conveyor roller comprises a right circular tubular member 1 having an end cap 2 located in each end thereof.
  • the end cap has a body portion 20 formed of a suitable plastics material such as polyurethane which has an axial hole 3 therethrough which is adapted to have a support shaft 4 passing therethrough.
  • the tubular member 1 and end cap 2 are supported on the shaft by means of a roller bearing 5 which is press fitted onto the shaft such that no relative rotation is possible between the shaft and the inner race of the roller bearing.
  • a stepped formation 6 in the body portion 20 is adapted to abut the outer race of the roller bearing in the assembled condition and a lock washer 7 located in a groove formed in the shaft is adapted to prevent relative movement of the end cap to the shaft.
  • the roller bearing 5 Located within the axial hole 3 are a plurality of seals 8 and seal housings 9 adapted to prevent the ingress of foreign particles into the roller bearing 5.
  • the roller bearing 5 will be lubricated by a suitable lubricant in use.
  • the outer peripheral surface of the body portion 20 has a stepped formation as shown at numeral 10 which provides an abutment surface against which the tubular member 1 abuts when the end cap 2 is correctly located within the end of the tubular member.
  • the operatively inner face of the body portion 20 has an annular rim 11 integrally formed therewith on the radially outer edge thereof.
  • the inner surface 12 of the rim tapers divergently away from the outer face of the end cap 2.
  • the tapered surface 12 has an angle of taper of approximately 15°.
  • a ring shaped element 13 (comprising a second portion of the end cap) has a cooperantly tapered radially outer surface 15, the ring shaped element being adapted to seat on the tapered surface 12.
  • the ring shaped element 13 is movable towards and away from the body portion 20 by means of three screws 14 which pass through the body portion 20 into threaded engagement with threaded holes formed in the ring shaped element 13.
  • the ring shaped element 13 can be caused to move towards and away from the body portion 20. As shown in Figure 1 the ring shaped element 13 is in engagement with the tapered surface of the annular rim 11. By moving the ring shaped element further towards the body portion 20, the two tapered surfaces will engage causing the annular rim 11 to move radially outwardly frictionally to engage its radially outer face lla with the inner wall of the tubular member 1.
  • the tubular member will be formed from steel or the like or alternatively that it will be formed from an unplasticised polyvinylchloride or like plastics material.
  • Unplasticised PVC is considered particularly advantageous as it is relatively wear resistant and it is capable of absorbing at least some of the shocks and jolts generally associated with conveyor rollers.
  • the wall of a steel tubular member will generally be thinner than the wall of a plastics tubular member of comparable load bearing characteristics.
  • a steel tubular member is shown at numeral 16 whilst a thicker walled plastics tubular member is shown at numeral 17.
  • the end cap will be correspondingly shaped.
  • a combination of plastics and steel tubular members may be used and this configuration is shown at numeral 18.
  • screws 14 will be three screws evenly spaced around the shaft 4 as shown in Figure 2. By gradually screwing the screws into the ring like element 13 the said ring like element may be evenly drawn into wedging engagement with the surface 15.
